IMPROVEMENT IN MECHANISMS FOR OPERATING DOFFER-COMBS.

Specification forming part of Letters Patent No. 166,405, dated August3, 1875; application filed April 23, 1875.

To all whom it may concern:

Be it known that I, JOSIAH K. PROCTOR, of Philadelphia, in the county ofPhiladelphia and btate of Pennsylvania, have invented certain new anduseful Improvements in Dotfer-Uomb Mechanism; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference bein g had to the accompanyingdrawings, which form part of this specification, in which- Figure 1 is aperspective, partly broken away; Fig. 2, a horizontal section; Fig.3, avertical section of the cone eccentric, block, and stirrup; Fig. 4.; adetail elevation of the cone eccentric, block, and stirrup.

The nature of my invention consists in the peculiar construction andcombination of parts, as hereinafter fully described.

Referring to the accompanying drawing, A shows the oil well or box,formed with drip-cups a a. B is the combshaft, to which a rapidreciprocating motion is to be communicated, and G is a revolving shaft,provided with a pulley-wheel, c. .A is a screw-hub, located in one sideof the box A, having an elongated socket, a, in which the shaft G has anend bearing. 0 is an eccentric cone formed on the shaft 0. D representsa yoke fitting in the box A, and formed with an end enlargement, cl,having an opening for the passage of the end of the comb-shaft journalB, and made fast in said opening by means of a set-screw, d, saidjournals B having bearings at (L2 a in the box A. E is a block slidinglongitudinally in the yoke D, said block having a conical opening, 6, tocoincide with the cone 0, and flaring correspondingly on-the outside toconform to the taper of the opening in the yoke, as shown plainly inFig. 3.

The effect of this construction is as follows: A rotary motion beingcommunicated to the shaft 0, the cone 0 is caused to rotate in the blockE, said block moving to and fro in the yoke D, at the same time rockingthe latter, and conveying a reciprocating. motion to the journal B andshaft B. Lost motion of the cone 0 and block E is taken up by screwingin the nut or hub A, causing said cone to move in the block, and theblock to move farther into the yoke D.

In order to keep the forward end of the yoke D true in the box A, saidbox is formed with a rib, a against which the side of the yoke impinges.F is the lid of the box, secured in place by screws f f, and providedwith an opening, f through which access may be had to the set-screw (1,said opening being closed by a stopple or plug, f The shaft B terminatesin a flange, b, a similar flange, b terminating the journal B, and thetwo flanges being held in close contact by bolts b passing through around opening in the flange b and a segmental or curved slot in theflange b,- so as to permit the adjustment of the shaft B. Said shaft Bismade T or other form, of angle-iron, combining lightness with strength,and preventing the shaft from springing away at its center from thecylinder, thus obviating a difficulty heretofore encountered with shaftsas ordinarily constructed of round iron. Gr represents one of the armsfor sustaining the doffer-comb H, said arm being made adjustable. Hrepresents a telescopic extension of the arm G, fitting in a socket, gand held in place by a set-screw, g".

The advantages of the foregoing construction are briefly as follows: Thecenter or re volving shaft and the journal of the combshaft both runningin the same box, the latter is thoroughly lubricated without any extraexpenditure of oil, and the parts are made more compact than if saidjournal were exterior to the said box. The combination of the eccentriccone, sliding block, and yoke affords very superior means fortransmitting a fast reciprocating motion to the comb-shaft from thecenter or revolving shaft. The comb-shaft, being constructed ofangle-iron, can be made very strong, and at the same time very light,permitting a very rapid motion to be communicated to it without causingit to spring away at its center.

and arranged for operation substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this15th day of April, 1875.

JOSIAH K. PROOTOR.
